" "APPARATUS FOR VENEERING BRICKS.

SPECIFICATION forming part of Letters Patent No. 772,828, dated October 18, 1904.

Application filed May 24,1904. Serial No. 200,500. (No model.)

To all whom it may concern:

Be it known that I, EDWARD Ro FE, a sub- Mount Savage, in the county of Allegany and State of Maryland, have invented new and useful Improvements in Apparatus for Veneering Bricks, of which the following is a speciother clay products with engobea mixture of clay and coloring-matteris to immerse them .by hand repeatedly in a watery mixture of engobe, allowing them to. dry between each immersion. A bar of clay has also been coated with engobe in a thick plastic condition'by applying it to the surface of the clay bar as it emerges from the forming-die, the

clay bar and engobe passing through an open-- ing in a plate called a slicker, which spreads the engobe evenly over the surface of the bar,

The ob ect of my invention is to improve this form of'apparatus for applying engobe by making the slicker vertically adjustable with reference to the clay bar, that the coating of engobe may be regulated in thickness and forced to adhere positively to the surface of the bar of clay. My slicker is adapted for application to any form of machine making a continuous clay bar. It may also be applied 7 to a table over which the clay bar passes. The adjustment of the slicker can also be readily made or the slicker entirely removed without stopping the machine.

Referring to the drawings, Figure 1 represents a front elevation of a clay-bar forming machine with my improvement applied thereto. Fig. 2 is a plan view thereof; Fig. 3 is a diagrammatic view showing the application of engobe to a clay bar in connection with my invention.

Similar letters refer to the same parts on the several figures.

A indicates the cylinder of a clay-bar machine with a filling-hopper B and a mouth or forming-tube C, by which the outcoming bar D of clay receives its shape. 4 r

E E are two rods, preferably square in crosssection, attached to the flange c of the mouthpiece C in its horizontal diameter. The

rods E E extend forwardly beyond the mouthpiece or forming-tube C for a suitable distance and support a slicker F.

. As shown in Fig. 1-, the slicker F has a top f and two sides f f, which surround three sides of the clay bar D. Projecting laterally from each side f f is a flange f through which are formed vertical slots f 3 for the rods E to pass through. Bolts Gr. threaded into the flanges f at their tops and bottoms, pass into the slots and bearagainst the upper and lower surfaces of the rods E. When the bolts G are turned in well-known manner, the slicker F will be raised from or broughtcloser to the clay bar D. The proper space between the slicker and the clay bar having been obtained, the bolts G are tightened on the rods E, fastening the slicker in place.

Reference to Fig. 3 will show that the top f of the slicker lies at an angle to the surface of the clay bar D, the rear edge being higher than its forward edge. As thus arranged the engobe deposited on the clay bar and brought beneath the slicker is pressed against the bar form or slicker, rods projecting from said machine, supporting said engobe-applying plate or slicker, and means for adjusting the said plate or slicker on said rods.

2. In an apparatus for veneering or coating bricks and the like, a clay-bar-forming machine, combined with an engobe-applying' form or slicker, rods projecting from said machine, supporting said slicker, perforated flanges on said slicker through which said rods 10 pass, and bolts threaded in said flanges hearing against said rods.

In testimony whereof l afiix my signature in presence of two witnesses.
